Differential Global Positioning System (DGPS)
DGPS is an enhancement to Global Positioning System that provides dramatically improved accuracy, from the 15-meter nominal GPS accuracy to about 10 cm in case of the best implementations.
Land & Water use DGPS to accurately monitor the precise location of dredging equipment enabling dredging operations to be conducted with extreamly high levels of accuracy.
This is best described in the video below:
DGPS uses a network of fixed, ground-based reference stations to broadcast the difference between the positions indicated by the satellite systems and the known fixed positions. These stations broadcast the difference between the measured satellite pseudoranges and actual (internally computed) pseudoranges, and receiver stations may correct their pseudoranges by the same amount. The digital correction signal is typically broadcast locally over ground-based transmitters of shorter range.
